CADS ReSlope is a leading slope stability software package for calculating the factor of safety of earth slopes. The basic software module deals with unreinforced slope analysis using Bishops simplified method and circular slip surfaces. An additional optional module offers further methods of analysis; piezometric grid definition and the ability to analyse non-circular slip surfaces. A further optional module adds the ability to analyse reinforced soil including the use of tie back wedge analysis and two part wedge analysis.
